The world’s first piloted flight of an electrical plane powered by liquid hydrogen has taken place.
H2FLY, the Stuttgart Germany-based developer of hydrogen-electric powertrain methods for plane introduced it has efficiently carried out 4 flights from Maribor, Slovenia, powered by liquid hydrogen as a part of its flight check marketing campaign, together with one flight that lasted for over three hours.
They imagine the flights lay the muse for long-range, emissions-free flight, with liquid hydrogen doubling the vary of the HY4 plane to 932 miles (1,500km), in comparison with utilizing gaseous hydrogen which is far heavier.
“Outcomes of the check flights point out that utilizing liquid hydrogen rather than gaseous hydrogen will double the utmost vary of the HY4 plane from 750 km to 1,500 km, marking a essential step in direction of the supply of emissions-free, medium- and long-haul business flights,” the corporate stated in an announcement.
During the last 12 months, GNN has saved abreast of all hydrogen electrical flight milestones, because the liquid gasoline is the one present possibility for decarbonizing aviation. In December, Rolls Royce and EasyJet efficiently examined a hydrogen engine for a jumbo jet.
This yr, Join Airways and Avia have each efficiently flown plane utilizing inexperienced hydrogen gasoline, the latter onboard a 40-seater ATR 72-600 regional plane throughout a 15-minute FAA Airworthiness Certificates flight, and the previous throughout a 10-minute flight with a 19-seat plane referred to as the Dornier 228.
In Could, GNN reported on a Harmony-like supersonic jet beneath improvement that will use inexperienced hydrogen as its gasoline supply. The corporate Destinus is working with hydrogen as a result of it’s a lot lighter than fossil jet gasoline, and weight issues are a key requisite for supersonic journey.
Now nonetheless, H2FLY’s piloted HY4 demonstrator plane fitted with a hydrogen-electric gasoline cell propulsion system was capable of conduct exams upwards of three hours of flight time, making the German firm’s progress the outlier within the discipline of hydrogen aviation.

In contrast with pressurized gaseous hydrogen storage, H2FLY’s use of liquified, cryogenic hydrogen allows considerably decrease tank weights and quantity, due to this fact resulting in elevated plane vary and helpful payload.
“This achievement marks a watershed second in the usage of hydrogen to energy plane,” stated Professor Josef Kallo, co-founder of H2FLY. “We at the moment are waiting for scaling up our know-how for regional plane and different purposes, starting the essential mission of decarbonizing business aviation.”
